Danetki Qwen3-0.6B — Fine-tuned for "Данетки" (lateral thinking puzzles)

A Qwen3-0.6B model fine-tuned with QLoRA for playing Данетки — a Russian lateral thinking puzzle game. The host describes a mysterious situation and players ask yes/no questions to figure out what happened. This model acts as the host, answering player questions.

Try it in your browser — runs entirely client-side via WebGPU, no server required.

Task

Given a puzzle context (condition + answer) and a player's question, respond with exactly one word:

Quick Start

from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "lifeart/danetki-qwen3-0.6b"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id, torch_dtype="auto", device_map="auto")

# Override chat template to standard chatml (no <think> tags)
CHAT_TEMPLATE = (
    "{%- for message in messages %}"
    "{{- '<|im_start|>' + message.role + '\\n' + message.content + '<|im_end|>\\n' }}"
    "{%- endfor %}"
    "{%- if add_generation_prompt %}"
    "{{- '<|im_start|>assistant\\n' }}"
    "{%- endif %}"
)
tokenizer.chat_template = CHAT_TEMPLATE

messages = [
    {
        "role": "system",
        "content": "Ты ведущий игры Данетки. Тебе дан контекст и вопрос игрока. Отвечай ТОЛЬКО одним словом: Да, Нет, или Не важно."
    },
    {
        "role": "user",
        "content": (
            "Контекст: Человек зашёл в бар и попросил стакан воды. "
            "Бармен достал пистолет и направил на него. "
            "Человек поблагодарил и ушёл.\n\n"
            "Разгадка: У человека была икота, и бармен испугал его, "
            "чтобы она прошла.\n\n"
            "Вопрос: Человек хотел пить воду?"
        )
    }
]

text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(text, return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_new_tokens=10, temperature=0.1, do_sample=True)
response = tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:], skip_special_tokens=True)
print(response)  # "Нет"

Important: Override tokenizer.chat_template with standard chatml (as shown above). The model was trained with this template — Qwen3's default template includes <think> tags which are incompatible.

Input Format

Model Details

Training Details

Training Data

~183K examples (train) / ~28K (val) from:

• Scraped Данетки Q&A pairs — question-answer pairs parsed from puzzle threads on danetka.ru, where real players asked questions and hosts responded. Responses were classified into Да/Нет/Не важно categories.
• DaNetQA reformatted to Данетки style — the Russian DaNetQA reading comprehension benchmark, reformatted into the puzzle host chat format.
• Context perturbation augmentation — augmented examples with perturbed contexts to improve robustness.

Data Quality

• Rebalanced class distribution: ~36% Да / ~36% Нет / ~28% Не важно
• Cleaned NV labels: removed uncertainty responses ("не знаю", "некорректно") misclassified as irrelevant
• Removed cross-puzzle negatives (caused label noise)
• Stratified Нет downsampling to match Да count
• НВ oversampling (target 25%)

Training Configuration

Benchmark Results

Evaluated on 190 test questions across 25 puzzles (greedy decoding):

Per-class metrics (with facts):

Known Limitations

• Slight "Да" bias: recall 91% for Да vs ~60-70% for Нет/НВ
• Only responds in Russian
• Quality depends on how well the puzzle context covers the player's question

Framework Versions

• PEFT 0.13.0+
• TRL 0.12.0+
• Transformers 4.45.0+
• PyTorch 2.1.0+
